City scanners

City Scanner:

A small and rather simple peice of combine technology which hovers around city streets locating citizens within the population for the combine overwatch. The 'shield scanner', the city scanners sister machine, is extremely similar although it has armour and a claw for carrying and depositing hopper mines. Both scanners have large electronic photographic reals which when required speed up and quickly snap up to 5 photographs at a time, this is located at the rear of the device. The scanners main use is for quick sweeping of areas and detecting dirupturs or citizens inwhich the combine overwatch require. The photographic film immediately sends the footage away to the overwatch nexus or combine citadel to be analysised and alert combine forces of the person. They appear in Half-Life 2 in the begining patroling City 17 and The Canals, later in the Citadel, Scanners appear also in Episode One in the city streets again, spying on the citizens for their escape plans. In Episode Two, they are seen in the route to White Forest but are not really fought. Could they be in Episode Three?

Sometimes these Scanners can sky dive if they are damage to much.
